As what was mentioned awhile back, more and more manufacturers have used raspberry ketones in their weight loss product since the time the substance was mentioned in the Dr. Oz show. With that response from producers, it is really very hard to assess which one is an authentic product or not. Perhaps, the following sets of criterion may help you decide.

#1 – Look for an all-natural raspberry ketone product. Many laboratories produce the synthetic form of raspberry ketones because it is simply hard to extract as much ketone in a single pile of raspberries. Therefore, you have to take the challenge to look clearly into how the product is manufactured before it became raspberry ketones for weight loss.

#2 – Look into other ingredients combined with the supplement you want to purchase. Are there other synthetics or all the other ingredients are natural? You have to make sure you go for all-natural ingredients.

#3 – Look for overall value of the product. Of course, you can see this through the benefits section of the item. This is commonly found in websites devoted to promoting the product. From here, you should look into the price attached to your purchase.
